Is it possible to have code snippets that I can create one time and I can use for all new projects instead of creating the same ones all the time again ?
Thanks in Advance
In Xcode code snippets you create are available to all projects by default.
From the Xcode Help article "Create and use code snippets" this is how to create one:
In the source editor, select the code fragment you want to make into a snippet, then choose Editor > Create Code Snippet.
Alternative, just choose Editor > Create Code Snippet.
